Also ENIAC was a single computer, while Colossus was in series production - there were ten of them, plus one being built at the end of the war.

Insufficient information to say whether this is literally true, but if you don't answer "science" you lose 15 points, which is at least a very serious blow to your chances of passing.

No, I really do mean that they used the disks as ROM. No writing to it. This worked because you can just put the stack and heap at a difference position in the memory map from the executable code.

The earlier Z80-based RML 380Z and 480Z machines from the same company were interesting as well. They were said to be the only computers designed to work with a boiled sweet shoved in the disk drive. They ran MP/M and CP/NET (effe

The Psions could do execute-in-place, including for third party software on ROM SSD - i.e. they did not have any fundamental distinction between working memory and disk storage.

The comma operator does exist, of course, but I've never heard of the comma in the context of C variable declarations being described as an operator, nor does a web search on "comma type operator" return any results. It doesn

As I remember it (from 40+ years ago, and well before dark energy was discussed), lambda naturally arises as a constant of integration in GR rather than being "invented" as in the usual story. Assuming this to be true, I'd su

I'm guessing that you have newRPL. Have you tried putting DB48/DB50n firmware on it? That does have graphics (and RPL). I haven't had time to get familiar with mine, so I can't comment further on capability.

I'd advise not doing "int* c" as it is misleading. Consider int* a, b; This looks as though it is equivalent to int* a; int* b; but actually means int* a; int b; Most people trying it your way hit this issue fairly quickly an

Both of those are things you could rig up yourself, which is the point of RPi. If you're interested in finding suitable touch pads, have a look at the ergonomic keyboard community as they do a lot of fabrication and integration.

There were a couple of aftermarket systems for the Psion as well. Normally the keyboard was better, but writing on the screen turned out to be easier in a bumpy taxi.

The closer you get to London, the more it matters. Money is not central to the system: it is possible and even common to be in one of the middle classes with virtually no income. However this may not work for the upper class since lack of m

Not really a computer though - they didn't exist in the USA at the time. If I remember correctly it was a series of IBM calculating devices chained together.

Vastly more than hundreds. For instance I have an HP-65 ( https://en.wikipedia.org/wiki/HP-65 ), a programmable pocket calculator from 1974. It's collectable, but not rare. It is built with similar objectives: low p

Not sure if it's still the case, but when I visited, they handed you a button to single-step through the program. You actually get to operate it, at some level.

One thing I like about the UK is the concept of regulated competition. The purpose is to ensure that there is always a competitive market place - so for instance in Internet technology, wholesale provider provides DSL layer 1/2 to mult

That is true now, but remember how far back this was. I was programming Modula-2 on CP/M - our lab standardised on the Amstrad 8512 for control / data acquisition for cost reasons. Early PCs existed, running MS/DOS, so you c

by tengwar2 2y ago
I found Modula-2 to be annoying to use, not for any deep reason, but because of its use of block capitals for keywords, and a confusing nomenclature for casting. It does actually matter that a language is comfortable to write.

One that never seems to make the list, but is worth considering: Excel, the only popular functional programming language! Not the VBA stuff, but the formulaic language of the spreadsheet itself.

Have you tried RPL (reverse Polish Lisp)? It's on later HP calculators, and it's pretty elegant for a small-machine language. The type system includes matrices and functions.

Is there a way of trying it in a simulator free, or are all the implementations commercial? I appreciate that I could use Wikipedia, but sometimes you end up going a long way down dead ends that way, so I hope you don't ming my asking.

Similar in the UK: employers can offer a defined benefit pension plan (usually based on something like 1/60 of final salary time number of years worked) or more commonly now a defined contribution scheme (invest in to a market-based pe

Your experience is probably of American conservative evangelicals. Even within that triple subset I could find you people deeply interested in the origins of texts (e.g. the translators responsible for the NET Bible ( http://netbi

I would want to see a source for this figure, to establish it as true before discussing whether it is justified. The Spectator has acquired a bit of a reputation for right-wing polemics.

Historians don't have a year 0, astronomers do. In fact the historical calendar is a bit messy for other reasons, e.g. the year beginning in April rather than January for a long time.

It's something you can get used to. A concert pianist can have 2-3 notes chasing each other down his/her arm. Myelinated nerve fibres are fast (the physiology is really interesting), but still has limits. Latency is more important
